The photo below is my Hay bale farrow huts. 8×9 space with large FREE Round bales. Thick layer of woodchips, sawdust and dry straw. Free plywood for roof and free billboard tarp to cover. The who system creates a compost effect. At -10° F outside its 50 to 55 inside. I build a 14× 20 hay hut for all the breeders and then as they come to their farrow date each momma get theit own birth hay hut.
No neee for heat lamps
With that said its important to have a good heritage breed that is winter hardy and the Gloucestershire Old Spot and red wattle are. I choice pick winter hardy pigs.
Its as regenerative as it get. The hay will be spread out and used for hay milk cover for gardens and my compost system. I sell hay/manure compost to my community as well.

Hello, I get a free supply of Spent Brewers grains from a local brewery. Counter to what many pig producers will tell you, pigs can be raised on spent grains alone with added minerals. I give them about 3 lbs of hog mineral just twice a week in the grains.
If the brewery is running low I supplement with GMO free rolled corn, just 3lb per pig.
In all my adult breeders on a yearly basic only cost me about 100$ to feed plus my gas to pick up the grains. Many people are amazed how little they eat. I have specifically chosen the best pigs from my litters and breeds making a pig that can thrive of little feed intake. My feeders in the summer months forage on pasture and get only 5lb of 16% grower and I have a finish rate of a 300lb live weight pig at 8 months.
They also get pumpkins and squash from Oct through Dec.

Yes. I raise 13 sows 2 boars and 20+ feeders. I farrow out over 200 piglets and primary sell feeder pigs in the spring and fall here in North Central WI. I raise Gloucestershire Old Spots & Red Wattles.
Its my goal to be WI go to for the best Heritage pasture/woodland feeder pigs.

I linked a photo of my winter Farrow system.
I live in North Central Wisconsin.
I source free old large round hay bales.
I place the bales in 8×8×4 hut setting. Use free old plywood/wood for roof then free billboard tarp on top.
Inside I put 6 inches of woodchips, 3 inches of dry shaving and 12 inches of dry straw.
The entire system is composting from the ground goat the bale.
At -10° F outside temps inside will be 35 to 40° due to the heat release from compost. Add a layer of snow on top and drift on side up to 50°  
I place a pc of plywood in ths front and allow for a small door but close it at night if temps go below 0°
I raise, breed 13 sows/gilts have two boars and raise out 20+ feeder in hay huts as well all winter.
Its important to have a good heritage breed if your are over wintering any pig.
I raise Gloucestershire Old Spots and Red Wattles.
